In their final days in Tokyo, Jeurgen Horn and Mike Powell took in a night at Shinjuku’s Robot Restaurant. The decor amazed them, but that was just the beginning.

Now, however, it’s showtime. You and your new friends head into the underground theater, take your seats, and await for the spectacle. Soon, the lights go out, the speakers switch on, and giant vehicles appear on either side of the narrow stage, ridden by ladies dressed as Amazonian war princesses from the year 3000. They’re pounding on drums, rotating around the stage, screaming and dancing to the music, and you’re just like… confused. What the hell is happening? It’s hilarious, ridiculous, impressive, overwhelming and pointless in equal measure.

And that’s just Act One! The show encompasses robot boxing, an alien-eating shark, and more weirdness that you can read about (and see videos) at For 91 Days.
